Lacunar infarction is a type of ischemic stroke, which can be simply explained as the blockage of small blood vessels. It generally belongs to one of the categories of ischemic strokes, which also include large vessel blockage and cerebral embolism. Lacunar infarction specifically refers to blockages in small blood vessels, and this type of stroke primarily occurs due to these small vessel blockages, and it is known as lacunar infarction.

Precautions for Stroke Patients Using Mannitol

Patients with stroke, if experiencing cerebral hemorrhage, extensive cerebral infarction, or cerebral embolism, can develop cerebral edema. In such cases, it is necessary to use mannitol for dehydration to reduce intracranial pressure. Therefore, it is crucial to strictly determine the appropriate indications. For patients with cerebral hemorrhage, cerebral embolism, or extensive cerebral infarction, the peak period of cerebral edema generally occurs between five to seven days, during which time mannitol should be used to lower intracranial pressure. If the acute phase has passed, then there is no need to use mannitol. For some patients, using mannitol weeks later not only lacks therapeutic effect, it might even worsen the condition. Additionally, when using mannitol, it is important to monitor the patient's renal function. In patients with renal insufficiency, the use of mannitol may exacerbate renal damage, so monitoring changes in renal function is essential. (Please use medication under the guidance of a doctor.)

What is good to eat after a stroke?

Stroke primarily refers to cerebrovascular diseases, among which cerebral infarction has the highest incidence rate. Regarding diet after experiencing a cerebral infarction, it mainly falls into two categories: The first category is medications. If it is a cerebral thrombosis, it is crucial to strictly control blood pressure and blood sugar using appropriate medications. Additionally, it is necessary to take medications to prevent the recurrence of thrombosis. These medications primarily include antiplatelet agents and drugs that regulate blood lipids to stabilize plaques. Furthermore, traditional Chinese medicines that invigorate the blood and remove stasis can also be used. These medicines also help to improve blood circulation. In terms of diet, it is essential to follow a low-salt, low-fat diet, avoid overly greasy foods, and eat plenty of fresh vegetables and fruits regularly. High-quality proteins should also be included, such as drinking milk and eating beef. Whole grains should not be omitted to ensure a balanced diet and promote recovery.

What does "brain stroke dnt" mean?

The term "DNT" refers to the time from when an acute stroke patient arrives at the hospital to the start of intravenous thrombolytic treatment. Both domestic and international guidelines recommend the DNT to be within 60 minutes—the earlier, the better. This standard was established by the National Health and Family Planning Commission. The time it takes for pre-hospital emergency care and in-hospital medication administration is approximately 60 minutes each. It is only by improving the time from pre-hospital treatment to medication administration within this golden window that we can enhance the patient's survival rate, prognosis, and quality of life, while minimizing disability rates.

The difference between stroke and cerebral infarction

Stroke includes ischemic stroke and hemorrhagic stroke. Ischemic stroke refers to cerebral infarction, while hemorrhagic stroke refers to cerebral hemorrhage. Symptoms such as limb weakness, slurred speech, or other neurological deficits should initially suggest the possibility of a stroke. Whether it is an ischemic or hemorrhagic stroke may be related to the symptoms, but a CT scan is essential. If a CT scan rules out cerebral hemorrhage, then cerebral infarction is more likely. The treatment varies with time; within 4.5 hours, if the conditions for thrombolytic therapy are met and there are no contraindications, and the relatives have signed an informed consent, thrombolytic treatment can be administered. If this time window is exceeded, this opportunity is lost, so it is crucial to seek medical attention immediately upon symptom onset.

Can a stroke be cured?

Stroke can result in sequelae such as deviation of the mouth, slurred speech, hemiplegia, numbness of extremities, coughing when drinking water, hoarseness, and difficulty swallowing. If the stroke affects a smaller area or is not located in a critical area, recovery tends to be better. However, if the infarct is large or occurs in a critical area like the brainstem, sequelae may persist, with partial function recovery possible within about three to six months.
